Looks good to me overall.

openbios missing.

ppc(64) missing (but you have slof above ;) ...
s390 too.

Hmm, I'd tend to ignore the aliases here (pc, q35, virt) and use
wildcards instead (pc-i440fx-*, pc-q35-*, virt-*).

I think that will be easier for libvirt to work with because it always
resolves aliases to actual machine types when storing them in the domain
xml.

I think "enrolled-keys" should better be a separate feature.
